RamCompare project releases final results

Updated results from a flagship research project have seen the re-ranking of some rams based on their carcase weight estimated breeding values (EBV).

Since preliminary results were released in November 2017, the RamCompare data set has been updated to include records from later-lambing flocks. Analysis has been modified to enhance the way hybrid vigour is taken into account which has caused a shift in the tables.

Penygelli, PAP1501802, a Texel ram bred by Alwyn Philips, has moved into top position for carcase weight EBV and overall carcase merit. The high-index ram sired by Boghouse Ultramuscle – a stock ram sold to RamCompare and progeny tested this year on the project farm.

Mr Philips said: “From the project’s inception, I immediately nominated my rams to be put to the test. It is a fantastic opportunity for them to be tested under commercial conditions against their top-performing peers.

“More and more pressure is put on commercial systems to reduce costs and to utilise grass and home-grown forages. My breeding decisions have focused on rams that perform exceedingly well in grass-based systems specifically in terms of muscling and growth.”

The Charollais breed has a new leading sire, with Logiedurno Navigator 13ZNN07239, nominated by the Crogham and Coldharbour Charollais flocks, sitting high in the overall rankings for carcase weight EBV and carcase value.

Among the Suffolk rams tested, Whichford First Class, bred by Bruce Cook, has now joined the list of the highest ranked Suffolk rams for carcase weight EBV.

RamCompare project coordinator Bridget Lloyd said: “With all rams from the first two breeding seasons now included, the final results tables show a slight repositioning. This will continue to happen each year as more rams are included in the trial.

More information on the rams with semen on offer – as well as the updated results – can be found at www.ramcompare.com.
